Every actor from The Last of Us games who appeared on the show (and who they played)

One of the signature features of The Last of Us is its fascinating take on the archetypal zombie apocalypse. Sure, people turn into scary monsters, but these ones are a little different than what we usually see; they’re living humans who are overtaken by a real-life fungus called cordyceps. The longer a person is infected, the worse the cordyceps infection gets, and the more they look like a hulking mushroom beast.

We get our first good look at one of these more advanced infected — called clickers — during the show’s second episode, when a pair of them attack Joel, Tess and Ellie while they make their way through a ruined museum. Just like in the game, the clickers are terrifying.

While the actors onscreen had no involvement in the game, the horrible, screeching noises that the creatures make may have sounded pretty familiar. That’s because the voice actors who provided the clicker sounds in the game, Misty Lee and Phillip Kovats for the female and male clickers respectively, also provided their voice talents for the creatures in the TV show.

Bonus cameo: Craig Mazin

Ok, so this next one isn’t someone who worked on the 2013 The Last of Us video game, but since we’re rounding up fun cameos it’d be silly not to at least mention it. The Last of Us show begins with an extended sequence showing the beginning of the cordyceps outbreak in Austin, where Joel lives with his daughter Sarah. It’s an intense way to start off the series, and ends in tragedy when Sarah is shot by a soldier just when it seems she and her dad have reached safety.

In the HBO show that soldier is played by Craig Mazin, one of the showrunners of The Last of Us. Mazin is covered from head to toe in tactical military gear, so this is a pretty sneaky one. As we said, Mazin didn’t work on the games, but he is a longtime fan them, which is a huge part of why this show got made in the first place.
